Centrica

Centrica plc is the FTSE-listed British energy and services group behind British Gas, the United Kingdom's largest household energy supplier, along with Bord Gais Energy in Ireland, Centrica Business Solutions, Centrica Energy (its wholesale power, gas and LNG trading arm) and the Hive connected-home brand. It sits across the whole value chain — upstream gas and storage at Rough, generation and battery flexibility, wholesale trading and route-to-market, retail supply to roughly ten million UK homes, and a field-service engineering business — after exiting North America with the sale of Direct Energy to NRG in January 2021 to refocus on the UK and Ireland. Its API posture is honestly closed: Britain mandated the smart-metering INFRASTRUCTURE (the licensed Smart DCC monopoly and the SMETS2 rollout) rather than a consumer data right, so Centrica has no Consumer Data Right, no Green Button and no standards-conformant consumer usage endpoint. The DESNZ non-domestic smart meter data access requirement that does bind it is discharged by a written request answered within ten working days, not by an API. Household consumers reach their own data only through the British Gas app and account login; business customers through the Energy360 DataView portal. The single publicly reachable developer surface found is the Centrica FieldOps Azure API Management developer portal — a partner field-operations platform in its development environment — and Centrica publishes no open grid or market data of its own, leaving that to NESO, Elexon and the DNOs.

Centrica publishes 1 API on the APIs.io network: FieldOps Identity API. Tagged areas include Energy, United Kingdom, Utilities, Electricity, and Gas.

Centrica’s developer surface includes authentication, sandbox, documentation, signup flow, API reference, engineering blog, and 23 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.

  description: Token-issuing API on the Centrica FieldOps API Management platform, published on Centrica's Azure API Management
    developer portal. A single POST /oauth2/token operation exchanges an OAuth2 client_credentials grant (client_id + client_secret,
    form-encoded) for a bearer access token used against the FieldOps WorkOrder, Opportunity and Appointment Slots APIs. Harvested
    verbatim from the portal's development environment on 2026-07-27; the production hosts api.fieldops.centrica.com and api-developer.fieldops.centrica.com
    both answer 403 anonymously. Calls also carry an Azure APIM subscription key (Ocp-Apim-Subscription-Key header or subscription-key
    query parameter).
